TO 'ALL PERSONS TO WHOM THESE PRESENTS SHALL COME:

Be it known'that L'LEVI H. Wnsr, of Cambridge, of the county of Middlesex, and State of Massachusetts, have made a new and useful invention having reference toRailway Gars or Carriages; and I do. hereby declare thesame to-be fully described in the following specification and represented in the accompanying drawings, of which- Figure 1 is a side elevation 'of a carriage truck or platform frame as provided with such invention, which has special reference to that for which Letters Patent No. 49,942 were granted to me on the 12th day of September, A. D. 1865.

Figure 2 is a section of the axle-box hanger and its spring extending from the platform.

In carrying out my present invention I dispense with. the truck frame for connecting and supporting the bearings of the boxes of the two axles of the railway carriage, and in lieu thereof I employ two levers and certain springs like such as represented on and in my patented invention as applied to the platform and truck frame of a carriage. In so doing I obtain the advantages of the truck frame with the additional ones of the elasticity appertaining to such springs and levers; also a better distribution of springs, together with other useful elfectsor results.

In fig. 1 of the drawings, Adenotcs-the platform or frame on which the body of-the carriage usually rests. G O are the wheels, and an: the axle-boxes on one side of the platform. Each axle-boxI form with two brackets g 9 extending from it in opposite directions to receive and support the shorter arms'of two levers DD, or two springs ff, such springs being arranged on and with respect to the brackets in manner as represented. ,The fulcra'of these levers are two springs c e, which are supported against abutments-k. k extended downward from the platform or car-body A. The longer arm of each leverwrests on the head of a bolt, which'passes up throughsuch arm near its extremity and goes through the platform'and a spring resting thereon, and iseonneeted with a metallic can or head to reston the spring, such bolts, springs, and caps being exhibited at c F d, c F d in fig. '1. Eaehaxlebox a is'suspended from the platform frame by means of a hooker hanger, I, which goes through an eye, it, projecting upward from the axle-box The hook orhanger is fastened to or on the platform, and carries a spring. 1', which is-arranged between the staple and the platform, and serves as anelastic support for the platform. The hookand eyeare to prevent the wheel-boxes from dropping away from the platform, or to keep them in their due relations when the platform may be raised or forced upward. Each springf may rest in sockets made in its bracket and lever, or the spring bracket andlever may be connected by a screw-bolt going down through them. I From the above it will be seen that for the truck frameiB represented and described in thespecification of my aforementioned patent, I have substituted a set of two levers D D, springs F F, rods 0 c", and their caps d cl. It will also be observed that the several, levers D D have their shorter arms and fulcra supported by springs, and that the wheel-boxes are supported by hangers which carry additional springs for the support of the platform frame. I

I doinot herein intend to claim the combination or the arrangement of levers D D" and the spring F, of each with the platform and truck frame, the same being as represented and claimed in my aforesaid patent. Nordod herein claim the combination and arrangement of elastic fulcra-with the levers D D, the platform and truck frames, and the springs F F, such being the subject of a Patent No. 55,603 granted to me on the 5th day of June, A. D. 1866. I 7

What I herein intend to claim as of my present invention is as follows:

I claim the combination as well as the, arrangement of the additional levers D D, their springs F F, and supporting rods 0 c, with the platform A,the wheel-boxes a a, and the levers D D, rods 0 c, and

springs F F.

I also claim .the combination as well as the arrangement of the springs fe F, and the suspension rod 0, with-the lever D, the 'wheel-box a, and the platform A.

I also claim the combination as well as the arrangement ofthehanger'l, and the staple h,-with the platform A, the wheel-box (1; and the supporting levers D or D D", applied to suchbox and platform.

" I also claim the combination as well as the arrangement of the springs z', with the hanger l, the box a, the

platform A, and the supporting levers applied to such platform and .the-wheel-box or'boxes, the whole being substantially as hereinbeforespecified.
